Acoustics

Speed: distance traveled in unit time (m/s)

Frequency: number of complete waves in one second (Hz)

Wavelength: distance between matching points on the wave (m)

Longitudinal: vibration parallel to direction of travel

Transverse: vibration at right angle to direction of travel

The sound is caused by objects that vibrate and make waves, these objects tend to vibrate due to an impulse that causes movement.

Small objects usually produce short-wave frequencies, which makes the sound be acute, and large objects produce long wave frequencies which makes it more heavy to heard.
